assignors to Beloit Iron Works, :Beloit, Wis, a corporation of WisconsinApplication November-2, 1950, Serial No. 193,585 Claims. -(Cl. 242-55)The present invention relates to' a Winder shaft puller and table andmore particularly to'means for removing a wound paper roll from awindingsapparatus and for removing a winder shaft from the roll.

In the manufacture of paper,the end product is a bulky, cylindrical,tightly wound roll of paper which, in the operation of modern highspeedpaper making machines, is too bulky and heavy for manual handling.Various types of roll handling equipment havebeen proposed forfacilitating removal of a wound roll from a winding or rewindingapparatus, and also for'removing a winder shaft upon which the roll isformed.

The prior art handling apparatusconventionally includes a conveyor orsimilar means for removing the roll from the shaft by retaining the shaft in fixed positionand moving the roll therefrom axially of-theshaft.It will be appreciated that such handling "apparatus requires arelatively heavy conveyor means for moving the-roll, as wellas'requiring a large amount of floorspace to accommodate the handlingequipment.

In addition, a new set of coresmust beslippedon the shaft before theshaft can be reused 'in a subsequent winding operation, andthe use'ofprior fixed shaft-type handling apparatus required themanual'positioning of new cores upon the shaft.

The present invention now'provides"animproved paper roll handlingapparatus whereinth'e shaftis axially pulled from a stationary rollby'th'e utilization of *a relatively small shaft'conveyor, ratherthanpulling the'roll from the fixed shaft as heretofore proposed.Generallyjthe present invention includes a roll table Positionedimmediately adjacent the roll Winding apparatus so as -to receive awound roll therefrom. The 'rolltableincludes 'atiltable apron bridgingthe' gap betweenfthe winding apparatus and the table proper, and powermeans for tilting 'the apron to move the roll to'itsfixed positionoverlying'a slot formed in the table.

When the roll is positioned withinthe table slot, a shaft conveyor ismoved to engage one end of the-shaft, and the conveyor isthenen'ergized'to pull the shaft from the roll. The table isalso'providedwithpower means for ejecting the roll from the table slot.The power ejecting means may either take the form of a movable tableportion for rolling the roll "ontoan associated Wrapping table, 'or aportion ofthe ro'lltablemaybelowered, so that the roll is deposited upon'a'supportingfioor surface.

Following removal of thefr'ollfrom'the table, a new roll core or set ofcores is positioned inthe'ro'llt able slot and the conveyor isre-energizediin the opposite direction to insert the shaft 'within'th'ecore. 'Afterthe core has been position upon the shaft 'by'm'ovement'o'fthe shaft into the core, the core is rem'oveilfrom'the tableforrepositioning in the windingapparatuseither by manually rolling'the corealong the table and apron surface or by energization of power'meanscarried by thetable for'this purpose.

It will be appreciated that the apparatus of the present invention mayalso be used *inconnectionwith 'coreless collapsible shafts as' well asthe more usual core-type winding shafts.

It is, therefore, an important object ofth'eipresent invention toprovide an improvedpaper'rollhandling apparatus wherein a shaft-isremovetl*fi-om'"the roll by "means of a shaft-pulling conveyor.

ice

Another object of the present invention is to provide an improved rollhandling apparatus including a roll table having a slot thereinforpositioning a paper roll, shaft pulling mechanism aligned with thetable .slot for removing a shaft from the roll while the roll isretained upon the table, with the shaft pulling mechanism also beingoperable to insert the shaft within a new core positioned within thetable slot.

It is a further important object of the present invention toprovideanimproved paper roll handling apparatus including a roll table adapted tobe positioned adjacent a roll winding mechanismfor receiving a paperroll from the winding mechanism, the table being provided with powermeans for positioning the roll thereon for removal of the roll shaft andfor ejecting the roll from the table after the roll shaft has beenremoved.

Still another important object of .the present invention is to providean improved paper roll handling mechanism in which a paper roll ispositioned upon a table so that the roll shaft may-be engaged by a shaftpulling mechanism which is vertically adjustable to accommodate theremoval of shafts from rolls .of varyingsize.

Yet a further important object of the present invention is to provide awinder shaft puller and table wherein a roll shaft may be removed from aroll positioned upon the table by utilization of a shaft conveyor, theshaftfree roll may be ejected from-the table, and the shaft pullermechanism utilized to reinsert the shaft within a new roll core.

An additional object of the present invention is to provide a windershaft puller and table for paper rolls having shafts extending axiallytherethrough and including power means forpositioning the roll'within atable slot, means for pulling the shaft from the roll by actuation of apower operated shaft puller mechanism while retaining the roll inposition within the table slot, power means for ejecting the roll fromthe slot, thereby removing the same from the table, means for reversingthe direction of movement of theshaft puller to insert the shaft withina new roll core, and means for removing the new core from the table fora subsequent winding operation.

It is a still further object of the present invention to provide a tablefor receiving a wound paper roll and including means for elevating andlowering the entire table and means for tilting aportion only of thetable to eject a roll therefrom.

Yet another object of this invention is to provide a shaft pullingapparatus including a shaft conveyor, means for elevating and loweringthe conveyor, and means for moving the conveyor in opposite lateraldirections to remove a shaft from a wound paper roll, to retain theshaft in removed position,-and to re-position the shaft for a subsequentwinding operation.

Other and further important objects of this invention will becomeapparent from the disclosures in the specification and the accompanyingdrawings.

As shown on the drawings:

In Figures 1 and 3, reference numeral 10 refers generally to a shafttable and puller assembly of the present invention which is particularlyadapted for utilization in conjunction with a drum-type paper rollwinder 11 including a pair of roll binding drums 12 rotatable aboutsubstantially horizontal parallel axes, one of the drums 12 being drivenby a suitable source of power. The drums 12 cooperatively supportthereon a paper roll 13 formed of successive layers of paper wound abouta core C peripherally enclosing a shaft S.

The supporting structure for the lower winding drums 12 includes (Figure3) a supporting beam 14 from which there projects an angled stop member15 including an upwardly projecting stop arm 16. A roll table 17 ismounted adjacent the winder 11 in spaced relation to The table 17includes a plurality of transversely spaced upstanding support brackets18 (Figures 2 and 3) which rest upon a supporting floor F. The brackets18 are provided at their upper forward portions with upwardly projectingextensions 19 which rotatahly journal a longitudinally extending apronaxle 20.

An apron 21 is provided to bridge the gap between the table supportingpedestals 18 and the winder support beam 14, the apron being formed of aplurality of separate elongated fingers 21a. The apron 21, when in itsnormal lowered position (Figures 3, 4, and 5), rests at its outer endupon the upstanding stop arm 16 hereinbefore described. Each finger ofthe apron 21 is provided with a dependent boss 22 at its inner end forrotatably receiving the axle 29 therethrough, and the axle carries,intermediate adjacent pedestals 18, a cam 23 having an arcuate exteriorcamming surface 24 and pivotally connected at its free end, as at 26, toan actuating rod 27 of a pneumatic or hydraulic cylinder 28. That end ofthe cylinder 28 remote from the cam 23 is pivoted, as at 29, to a lowersupporting bracket 30 resting upon the lower supporting floor-F.

The operation of the apron 21 will be appreciated from the foregoingdescription in that the paper roll 13 upon movement from the winder 11will be initially placed upon the apron 21 when the apron is in itslowered position as seen in Figure 3. Upon actuation of the differentialfluid pressure cylinder 28, the piston rod 27 of the cylinder will beextended beyond the cylinder to rotate the cam about the longitudinalaxis of the axle 24) as a pivot point, with the camrning surface 24 ofthe cam 23 contacting the undersurface of the apron 21, thus tilting theapron about the axle 2% and causing the roll 13 to roll from the aprononto the table proper as will be hereinafter described.

That portion of the table 17 upon which the roll 13 is placed followingelevation of the apron 21 is provided by a plurality of table bars 32having horizontal upper surfaces aligned with the upper surface of theapron fingers 21a when the apron is in its horizontal position, Theplurality of bars 32 are spaced along the length of the table and aresupported upon the pedestals 18 by means of longitudinally extendingsupporting beams 33 secured, as by welding or the like, to each of thetable bars 32 andto each of the pedestals 18.

Immediately rearward of the table bars 32, each of the pedestals 18 isprovided with a generally V-shaped notch 34, the inclined sides of thenotches having secured thereto elongated core cushioning bars 35.Immediately adjacent and above each of the cushioning bars 35, thepedestal carries I-beams 36 which project upwardly from the pedestals tocarry on their upper surfaces front andrear roll beams 37 and 38,respectively. The roll beams 37 and 38 are provided with adjacent,oppositely inclined inner beveled edges 39 which cooperate to form asecond larger notch directly overlying the first notch 34.

A curved roll kicker arm 42 is pivotally attached to a rearward portionof three of the pedestals 18, as at 43 (Figures 2 and 4), and the free,forwardly and upwardly extending ends of the arms 42 carry thereon theforward I-beams 36. The I-beams 36 thus merely rest upon the pedestals18 when in their solid line positions as illustrated in Figure 4, andthe forward I-beam 36 is adapted to be moved from its resting positionupon the pedestals 18 when the kicker arms are actuated.

Thus, it will be seen that the forward I-beam 36 is actually carried bythe roll kicker arms 42, with the weight of the I-beam 36 and theassociated roll beam 37, together with the roll 13 superimposed thereonbeing borne by the pedestals 18 only when the roll beam is in its normallowered position as illustrated in full lines in Figure 4. Actuation ofthe roll kicker arms 42 is accomplished by means of fluid pressurecylinder actuating arms 44 pivoted, as at 45, to an intermediate,forward portion of the arm 42. The actuating arms 44 are extensiblebeyond the associated cylinders 46 when the cylinder is energized, as byconnection to a source of fluid under pressure, and the cylinder ispivoted intermediate its length, as at 47, to an upstanding support 48carried by the floor F.

From Figure 2, it will be seen that a plurality of roll kicker arms 42are provided along the length of the roll table, and each of these arms42 is provided with its individual actuating cylinder, with all of thearms of these cylinders being simultaneously actuated to cause movementof the roll 13 from the roll support beams onto an additional rollsupport table 41 positioned immediately to the rear of the table 17.

After the paper roll has been moved onto the table 41, the shaft pullermechanism is reenergized to replace the shaft S within a new roll coreC, and the roll core is then placed upon the under winding drums for thereception of a new roll of paper. If, however, a coreless collapsibleshaft is used, the shaft is merely replaced upon the table 17 and thenmoved onto the under drums.

The mechanism particularly illustrated in Figure 3 of the drawings isutilized for this purpose, and it will be seen that there are provided apair of core arms 50 at spaced points along. the length of the rolltable. The core arms 50 are generally arcuate in shape and one end ofeach arm is pivotally supported, as at 51, by an upstanding arm supportpost 52. The other end of the arm is pivoted, as at 52a, to theactuating rod 53 of a fluid pressure cylinder 54 which is pivoted at 55intermediate its length between a pair of upstanding cylinder supportposts 56 projecting upwardly from the supporting floor F. That endofeach arm 50 secured to the cylinder actuating arm 53 is provided witha plane core contacting surface 57 which is moved 'upwardly'uponactuation of the cylinder 54 and pivoting "movement of the arm 50aboutits 'point 'of pivoted attachment 51 to contact the 'coreC,thereby'elevating the core to a positionupon the "roll support beam 37.The core pads '35 are cut away, as at 58- (Figure '2), to accommodatemovement of the core arms 50 'therethrough. After the core has been'pflace'd in the dotted position shown in Figure 3, it may then bereadily manually rolled upon the roll'support bars 3'2, and'moved overthe apron 21 to its position upon the =W'inder under drums -12.

"core supporting notches 34'onto the roll beams for later m'ovementacross =the'bridging bars 32.and the apronbars .21- onto the winderunder drums 12.

The above described procedure for utilization of the table :17 may bechanged slightly :as desired. As particularly :illustrated in :Figure :3Of? the drawings, it will be seen that a core and shaft, or corelessshaft, posiktionedwupon the shaft-cushioning bars 35 will 'be displacedwell "below the roll 13 borne by the roll beams 37 :and'38. Thus, thefollowing procedure "may be carried out; theshaft S and the 'corefQmaybe positioned .within themotch 34 to rest upon the core-cushion bars 35,then a vroll 13 may be superimposed thereon by actuation of the apron 21as hereinbefore explained. The shaft from the finishedroll -13 maythen'be-withdrawn, the roll ejectting arms llenergized to remove theroll from the table 17,*andIfinall-y the 'core'return arms 50 energizedto place the shafts of the core C upon the table bars32, as hereinbeforeexplained.

The shaft puller 40 is particularly illustrated .in Figures .1, 6 and 7of the drawings. Theshaft puller is utilized only after the roll hasbeen positioned upon the roll.beams -37 and 38 as hereinbeforedescribed. The shafts is-normally retained .within theroll .core .bymeans of shaft nuts 60 threadedly retained upon the shaft to tightlyclamp the core thereon. To remove the shaft, theshaftnut60 atone endofthe. shaft must be removed, 'sokthat the shaft may be pulled axially ofthe roll and the. associated core.

Theshaft S, after the roll has been placed in position -on..t he.rollbeams, is energized to pull the shaft from the roll. As best shown inFigures 6 and 7, the shaft puller includes two pairs of spacedsupporting pedestals 61, eachpair of which has linner opposing verticalguideways 62 slidably journaling guide carriages 63 therein.

Each of the guide carriages 63 (Figure 7) includes upstanding spacedguide posts 64 which are slidably received by the guideways 62. The.posts 64 are joined by a lower 'frame member 65 which rotatablyreceives an elevator rod 67. The lower free end of the'elevator rod .67.is threaded as at 68 and depends into a cylindrical lubrication housing69 closed at its upper end by packing nut 70. The extreme lower endofthe elevator. "rod '67, which is continuously threaded to its freeend, extends through a gear housing 71 into a second lubricatinghousing72having its lower end also closed by packing nut 73. The lowerthreaded portion 68'of the elevator rod 67 extends below the surface ofthe floor F and the "housings '69 and 72 are likewise located'be'low thefloor. The lower threadedportion 68 of the elevator. rod issurrounded-intermediate its length by an internally threaded gear-"nut74 which has'its exterior periphery formed as a worm gear"75 inmeshwith-a worm 76"keyed to a driven 's'haft 7-7.

=As shown in 'Fi'gure -'6, the shaft 7-7 is {connected by suitable"means, as byshaft'78, to one end of the drive shaft 79 of an electricmotor '80 supported upon a pair of transverselyspaced I-be'ams -81 whichalso ser-ve 'to=support the gear housing 71. The other end of the driveshaft 79 is'connected in a similar manner to a second driven shaft 77for driving a worm and worm gear arrangement within a second gear box 71for rotating the other ofthe elevator rods -67. It will be seen that thegear box 71 prevents vertical movement of the worm gear so that drivingof the worm '76 by energizatiomof the motor '80 will cause correspondingrotation of --the worm gear nut 74 to rotate the elevator shaft 67 byvirtueof its threaded engagement with the worm gear nut to causeelevation and lowering of the slide carriage 63. Thus, the slidecarriages 63 may be moved vertically in a path determined by theguideways -'62 formed in the upstanding pedestals '61 hereinbeforedescribed.

'The carriages 63, or more particularly, the-uprights 64 carry at theirupper portions side frame beams 83. One such side frame beam 83 iscarried by one of each pair of thepedestals 61, the frames '83beingsecuredto the pedestals by suitable means, as by bolts "84, and a pad-85is interposed between each pedestal and the associated frame member 83.The corresponding ends of the frames -83 adjacent the table 17 journaltherebetween a shaft 86 which is slidable lengthwise within a slot 86aformed in the beams to permit longitudinal adjustment of the shaftrelative to the frames. The shaft 86 carries a pair of sprocket gears 87and a clamping-plate '87a-is provided exteriorly 'of the frame forclamping the shaft and sprocket in a desired longitudinally adjustedposition.

An additional pair of sprockets '88 are carried by the frames 83adjacent the opposite ends thereof, the sprockets 88 being keyed to ashaft-89 journa'led between the frame members for rotation. The sprocket88 is driven by means of an electric motor 90, or other suitable sourceof power, mounted upon a motor support bracket 91 secured tothe sideframe members 83 bydependent legs 92. Themotor has a drive shaft 93 fortrans mitting motive power to a worm-type speed reducer 94 having adriving worm 95 geared to the shaft 89 to drive the same. Asprocketchain 96 is trained-aboutone of each pair of the sprockets '87and 88, and it will be seen that the driving of the sprockets 88 byenergization of the motor 90 will effect travel of the sprocket chain96.

A chain support plate 97 is secured to each of the frame members 83to'extend inwardly therefrom 'and'along the length thereof, as bestshown in Figures '6 and 9. The support plate 97 slidably receives theupper reach of the chain 96 thereon, so that sagging-of the upper reachof the chain, due to the chain weight, may be prevented. The lowerreturn reach of the chain is supported byone or more chain idlersprockets 98 secured .to the frame members 83 and dependingtherefrom.

As best shownin Figures 6 :and 8,.the chain carries a shaft-engagingpuller .100 which is secured to each of the chains 96 to extendtherebetween for movement therewith. The puller 100 comprises a bottomplate 101 bridging the chains and secured thereto by suitablemeans,.side plates 102 joined to the bottom plate 101 and projectingvertically 'thereabove, and spaced transverse plates 103 and 104, theforward transverseplate 104 having a-central arcuately bottomed notch105.

Also carried by the sprocket chain 96 are a plurality of shaft ipads 106comprising a metal block-or thelike having a depressed upper arcuateseat 107 and carrying lower angular brackets 108 attached to the innerextremities of the sprocket chains .96. Inasmuch as thejpads 106 areattached-to the inner surfaces of the chains 96, there isno-interference of the pads with either of the drive sprockets "8788 .orwith the idler sprockets 98. Accordingly, the pads 106 can passaroundthe drive sprockets and over the idler-sprocketwithout :interfering withthe chain drive. It will be appreciated that there is no possibility ofany interference by the shaft puller 100, inasmuch as this member merelytravels on the upper surface of the chain assembly, in other words alongthe length of the support beams 83, so that the puller is constantlysupported thereby and does not pass about either of the drive sprockets87 and 88.

In use, when a roll 13 has been positioned upon a winder table 17 ashereinbefore described, the shaft puller assembly is raised from itsdepressed position, so that the extreme shaft flange S at the drivingend of the shaft S is positioned between the transverse plates 104 and103 of the puller. It will be appreciated that this elevating movementis accomplished by the power means driving the elevator screws 67 toraise the guides 63 in their path determined by the pedestals 61.

Next, the motor is energized to drive the drive sprocket 88 through thespeed reducer 94 and the shaft S is pulled from the roll 13 byengagement of the shaft flange S with the forward transverse plate 104of the puller 100. During retractionof the shaft 8, the pads 106 arebrought into supporting engagement with the shaft S by their travel withthe sprocket chains 96, so that the shaft is supported at a plurality ofpoints along its length, as shown in dotted outline in Figure 6.

Following retraction of the shaft S, the roll may be removed from thetable 17 as hereinbefore disclosed, and the shaft puller assemblylowered by re-energization of the motor 80 to a height desirable forreinsertion of the shaft within a set of roll cores supported upon thetable, or for merely placing an expansible shaft upon the table.Following vertical positioning of the shaft, the motor 90 isre-energized in an opposite direction to return the shaft to the Windertable, the shaft being moved by contact of the terminal flange S thereofwith the rear transverse plate 103 of the puller 100.

In Figures 10-14, there is illustrated a second form of -winder tablesimilar to that hereinbefore discussed in of the pit, as by means of tiebolts. The frame members also aid in supporting upstanding lift frameguide plates 126 which are secured to the sides of the pit by suitablemeans, as by tie bolts 127, to extend in parallel spaced relation. Theguide plates 126 are provided with vertical opposed guide grooves 126a(Figure 10).

Additional lift frame guides are provided by side beams 12S carried bythe longitudinal I-bearns 123 at each end thereof and secured to the pitsides by tie bolts 129. The frame guides 128 provide inner upstandingguide posts 130 which carry on their opposed facing surfaces innergrooves,

to be hereinafter more fully described, for receiving correspondingportions of a lift frame.

The longitudinally extending I-beams 123 carry thereon an electric motoror similar power means 131 having oppositely extending drive shafts 132terminating at spaced gear boxes 133 and also at a central gear box 134.The

gear boxes 133 and 134 contain worm gear and worm drive mechanismssimilar to those hereinbefore described in connection with the gearboxes 71 of Figure 6.

The gearing housed in the boxes 133' drive elevator rods 135 projectingthrough the gear boxes and formed with screw threads in the same manneras the elevator rods 67, also hereinbefore described. The elevator rodcasings are lubricated by means of vertical lubricant lines 138.

' The upper ends of the elevator rods 135 terminate in enlargedcylindrical housings 139 which contact transversely extending lift framebeams 140 (Figure 11). .The transversely extending lift frame beams 140are joined by longitudinally extending lift frame beams 141 to define acompleted lift frame carrying thereon a roll table 142. The lift frameis driven for vertical movement by the energization of the power source131 and elevating or lowering movement of the elevator rods 135, thisvertical movement being guided by a transversely extending frame glide143, the edge portions 144 of which are received by the central guideslot 126a formed in the frame guide members 126 which are carried by theupstanding support posts 124. The lift frame is also guided againsttransverse movement by oppositely directed side guide members 145 havingoppositely directed edge portions received by similar slots formedin theguide members 130;

Thus, the lift frame is guided against transverse and longitudinalmovement during elevating and lowering of the same, and power means areprovided for effecting such vertical movement.

The longitudinal guide frame beams 141 carry a plurality of transverselyextending table pedestals quite similar to the pedestals 18 of theearlier described roll table 17. The pedestals 150 are each providedwith an upwardly projecting forward extension 151, each receivingtherethrough an apron shaft 152. The apron shaft has secured thereto forrotation therewith a plurality of apron fingers 153 cooperating todefine an apron 154 for serving the same function as the apron 21previously described. Each of the apron fingers 153 carries a dependentembossment 155 (Figure 12) receiving the shaft 152 therethrough andsecured to the shaft. The shaft 152 is provided. with a pair of spacedsquared shoulder portions which are engaged by correspondingly shapedsurfaces 156 formed by a rocker arm 157 secured to the shaft pivotallycarried at its free end, as at 158, by an actuating rod 159 of a fluidpressure actuated cylinder 160. The cylinder 160, of course, is providedwith an interior piston movable therein under differential fluidpressures to extend the actuating arm 159 to its position shown indotted outline, thereby turning the shaft 152 to tilt the apron 154 to asubstantially vertical position shown in dotted outline in Figure 12.The cylinders 160 are pivotally attached to an adjacent pedestal 150 bysuitable means, such as a pivot plate 161 welded or otherwise attachedto the pedestal 150 and carrying a pivot pin 162.

Immediately to the rear of the apron 154, the pedestal carries a pair ofupstanding channel irons 163 bearing on their upper surfaces a pluralityof table bars 164 in horizontal alignment with the apron fingers 153..The table bars 164 are adapted to receive a roll placed upon thefingers 154 and moved therefrom as the apron is elevated, in much thesame manner as hereinbefore described.

Each pedestal immediately to the rear of the table bars 164 carries atable pivot pin 165 passing through an embossment 166 formed on eachpedestal and received by corresponding depending embossment 167 formedon a tiltable table portion indicated generally at 170. The tiltabletable portion 170 is thus mounted for pivoting movement about the pivotpins 165 relative to each of the pedestals.

The table portion 17 0 is defined by a pair of .long'itudinallyextending transversely spaced channel irons 171 joined by upper andlower transversely extending irons 172 and 173, respectively, the lowertransverse iron 173 cartying the embossments 167 and the uppertransverse iron 172 having a notch formed therein intermediate itslength by a pair of inclined side irons 174 and a bottom iron 175.

The lower table iron 173 carries adjacent its rear end a plurality ofadditional depending pivot bosses 176.. The dependent bosses 176 areeach joined by a pivot pin 177 to an upper link arm 178 which in turn isjoined by a pivot pin 179 toa lower pivot link 180 which is pivoted, asat 181, to the rear I-beam 141. The pivot linkage formed by the links178 and 180 is adapted to be broken by an actuator arm 182 securedthereto and forming a part of a fluid pressure actuated cylinder 183 ofconventional type having a piston connected to the arm 182 andreciprocal within the cylinder 183. Each cylinder 183 is pivoted to asupporting plate 184 carried by the associated pedestal 150 It'will beseen that upon actuation of the cylinder 183, the rod 182 will bewithdrawn into the cylinder to break the linkage formed by the links 178and 180, thereby pivoting the rear table portion 170 about the pivotpins 165 joining the rear table portion to the pedestals.

The table 142 is also provided with power actuated stop means as bestillustrated in Figure 13. The stop means of Figure 13 comprises a stopplate 187 pivoted, as at 188, to the rear table portion 170 and pivotedat 189 to an upper link arm 190. The upper link arm is pivoted, as at190, to a lower link arm 191 which is attached at 192 to the rear I-beam141 for pivoted movement relative thereto. Here, again, the linkageformed by the arms 189 and 191 is adapted to be broken by actuating rod193 for a fluid pressure actuated cylinder 194 equipped with aconventional piston (not shown) for moving the arm 193 and pivotallyattached, as at 195, to a bracket 196 carried by the forward I-beam 141.

It will be appreciated that actuation of the cylinder 194 to move therod 193 rearwardly will break the linkage formed by the link arms 189and 191 to pivot the stop plate 187 relative to the rear table portion170. The stop plate 187 is provided with a laterally extending stop bar197 for preventing accidental displacement of a wound roll of paper 13from its position upon the rear portion 170.

The operation of that form of the table illustrated in Figures 10-14will be readily apparent from the foregoing description inasmuch as aWound roll of paper placed upon the apron 153 may be readily moved tothe notch defined by the plates 174 and 175 by actuation of the aproncylinder 160 to elevate the apron causing rolling of the tightly woundpaper roll over the table bars 164 to the notch.

After the roll has been positioned within the notch, removal of theshaft from the roll may be accomplished by means of a shaft puller, suchas the shaft puller 40 hereinbefore described in detail. Followingremoval of the shaft, the roll may be readily moved from its positionupon the table by tilting movement of the rear table portion 170. Thistilting movement is preferably combined with vertical movement of theentire table so that the roll may be gently deposited upon the floorsurface without possibility of injury to the roll.

More specifically, the table is lowered by actuation of the motor 131,as hereinbefore explained, and the table is tilted by breaking of thelinkage formed by the arms 178 and 180 by actuation of the cylinder 183,all as best shown in Figure 14.

During positioning of the roll upon the table, the stop plate 187 ismaintained in its raised position, as indicated in Figure 13, so thatthe roll may be maintained upon the table. However, when the table istilted to the position shown in Figure 14, the stop plate 187 is loweredby actuation of the cylinder 194, so as not to interfere with removal ofthe roll.

It will be understood that modifications and variations may be effectedwithout departing from the scope of the novel concepts of the presentinvention.

We claim as our invention:

1. A shaft puller and table comprising a table for receiving a bodyhaving an axial shaft therethrough and said table having a positioningrecess for retaining said body in predetermined position thereon, ashaft pulling conveyor movable both vertically and longitudinally withrespect to said body on said table in alignment with the axis of saidbody when seated in said recess, means on said conveyor engaging theshaft to remove the same upon 10 movement of said conveying meanslongitudinally away from said table and for repositioning said shaft insaid recess on said table upon movement of the conveying means in anopposite direction, and means for removing said body from said tableafter said shaft has been removed.
